Description

The Avada theme for WordPress is vulnerable to arbitrary file uploads due to missing file type validation when extracting zip files in the 'process_upload' and 'regenerate_icon_files' functions in versions up to, and including, 7.11.1. This makes it possible for authenticated attackers with author permissions to upload arbitrary files on the affected site's server which may make remote code execution possible.

Wordfence blocked 202 attacks targeting this vulnerability in the past 24 hours.
